3-7-2 Slave Output Data (*_SlvOutSta)
Name of Device Variable for CJ-
series Unit
Type R/W Description Function
*_SlvOutAreaCode USINT R Output area
code
Output area code (data from Master to Slave
CPU). Indicates the area to which the unit will
write PROFIBUS output data received from its
master.
00: No assignment made
01: CIO area (CIOxxxx)
03: DM area (Dxxxxx)
04: Work area (Wxxx)
05: Holding area (Hxxx)
08: EM bank 0 (E0-xxxxx)
09: EM bank 1 (E1-xxxxx)
10: EM bank 2 (E2-xxxxx)
11: EM bank 3 (E3-xxxxx)
12: EM bank 4 (E4-xxxxx)
13: EM bank 5 (E5-xxxxx)
14: EM bank 6 (E6-xxxxx)
15: EM bank 7 (E7-xxxxx)
16: EM bank 8 (E8-xxxxx)
17: EM bank 9 (E9-xxxxx)
18: EM bank A (EA-xxxxx)
19: EM bank B (EB-xxxxx)
20: EM bank C (EC-xxxxx)
*_SlvOutHoldBusErr BOOL R Data hold on
PROFIBUS fail
FALSE: Clear data to Host CPU
TRUE: Hold data to Host CPU
Indicates how the slave will behave on the Host
CPU I/O bus in the event the PROFIBUS data
exchange communication fails (e.g. comm.
watchdog timeout).
*_SlvOutIntelMd BOOL R Outputs Intel
mode
FALSE: Motorola (high byte first)
TRUE: Intel (low byte first)
Outputs Motorola/Intel mode
Indicates how the data bytes of a PROFIBUS
data exchange telegram are mapped to Host
CPU data words.
The values in *_SlvOutSta are provided by the
PROFIBUS master's Set_Prm telegram, and
indicated in *_SlvOutSta after both the Set_Prm
and Chk_Cfg telegrams have been accepted.
